A learning process
Animation takes a long time to nail down and do decently. The way you're going about it is, in my opinion, the ONLY way people should be doing things - which is by actually doing it. There's no better way to develop your skill than by getting your ass in front of the computer and piling down hour upon hour of animating.
Like another review said, I'd suggest trying a different art style since your characters look very primitive. Sometimes primitive works (South Park), and sometimes it doesn't. Unfortunately, this doesn't.
Nice experimentation with camera moves and scene changes. Keep up the hard work and you'll be drawing alongside the best of them.
